Severity ?
7.2 (High) - CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H
Summary
An issue was discovered in gdrv.sys in Gigabyte APP Center before 19.0227.1. The vulnerable driver exposes a wrmsr instruction via IOCTL 0xC3502580 and does not properly filter the target Model Specific Register (MSR). Allowing arbitrary MSR writes can lead to Ring-0 code execution and escalation of privileges.
